The website I made uses a frameset frame layout, which is divided into upper, middle and lower parts. The content of the upper and lower frames is fixed, but the content of the middle frame is different. I want the entire frame to share a scroll bar, so I use an iframe. In the nested frameset frame, I set the height in the iframe. The content of the page is different, and the height is also different. Is there any way to display all the content of the page? I've been struggling for two days, it's urgent, I'm waiting online! Please help me heroes!
Reply to the discussion (solution)
Dynamically calculate the height of the middle frame, add the upper and lower heights to the
, and assign them to the style.height of the outer iframe.
How to calculate dynamically? Could you please make it clearer?
h = document.documentElement?document.documentElement.offsetHeight:document.body.offsetHeight
Is this the height of the page in the subframe?
It’s strange that two iframes can share a scroll bar
